This two day course provides a follow-up to Linux System Administration (Part 1),
for those who wish to network their Linux systems. The course covers
the essential elements of configuring the network connection including
routing, and installing major services such as NFS, NIS and DNS, plus
other services. The SAMBA PC file and printer sharing software will
also
be briefly examined, as will the Apache webserver; working
installations
of both systems will be created. The course uses the Redhat and CentOS
Linux distributions.
Our Linux courses are suitable training for Linux LPI or RedHat Certification

Redhat. See Linux Advanced Administration Our Linux Utilities and Shell Programming
course is also a must for those concerned with system and network
security. First Alternative also offers an extensive range of Solaris
courses. If you are responsible for looking after day-to day
administration, then we can offer a very comprehensive range of Systems
Administration courses, right up to Solaris Advanced System Administration. Sheets
describing each of our courses, and current schedules, are available on

web-site interaction, and more. A very powerful and popular
programming/scripting language is available on Linux, known as Perl.
First Alternative offers two Perl courses, Perl Basics and Perl Programming.
PRACTICALS / TAKEAWAYS: Each student
leaves the course with their own set of training notes for the material
covered; around 120 pages per day of training.
